The University of the Free State is proud to announce the appointment of Nthabiseng Kotsokoane as chairperson of the International Federation of Library Associations and Institutions (IFLA) new Regional Council and member of the IFLA Governing Board 2021 – 2023.

IFLA is the leading international body representing the interests of library and information services and their users. It is the global voice of the library and information profession.

Nthabiseng Kotsokoane is currently the Assistant Director at the University of the Free State Library Information Services. She previously worked at Monash University for 10 years as a director of the library services. Ms Kotsokoane is a renowned library professional whose passionate efforts to advance library and information services in Africa and beyond are widely acknowledged. She has vast experience in serving at various committees regionally and internationally. She served as a member of the IFLA women information Libraries Special Interest Group. She was later elected by LIASA into the IFLA IT committee. She is the current IFLA Africa section Chair 2017-2021.

 

Serving the international library community

Nthabiseng is not only active in IFLA but on the African continent as well, she is the past chair for the African Library & Information Associations & Institutions (AfLIA) academic library section Chair and a member of the AfLIA Governing Board.

As IFLA’s Regional Chair her key role will be to in increase the presence of world regions in IFLA and IFLA’s presence around the world focusing on advocacy and building capacity. She will lead efforts to provide input on IFLA advocacy work and review success in developing the regional dimension of the IFLA Strategy, as well as work to promote IFLA membership and fundraising in the regions.

This will include coordination and development of Regional Division action plans, review Regional Division activities in the following regions Regional Council and Regional Divisions for Asia and Oceania, Europe, Latin America and the Caribbean, Middle East and North Africa, North America and Sub-Saharan Africa. With her passion of developing and mentoring new library professionals we are certain that this new role will be of benefit to the international library community.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
